« To anyone who is interested in learning more about the sky and every wonder it contains, this app is definitely worth a look! It explains, in detail, every constellation, star, meteor, satellite, and more. You can choose the desired location or use the geolocation tool. This app is incredibly interesting and much easier to use than other apps of its kind. You can even add a free option that allows you to see the location of the space station. Neat! »
